SlLK-REELING MACHINE.

EPECIEICATION forming part of Letters Patent No. 334,619, dated January19, 1886.

Application filed April 23, 1884. Serial No. 129,022. (No model.)

.To aZZ whom it may concern:

Be it known that I, EDWARD W. SERRELL, Jr., of the city, county, andState of New York, United States of America, temporarily residing atGhabeuil, in the Department of Droine, in the Republic of France, haveinvented a new and useful Improvement in Silk- Reeling Machines, ofwhich the following is a specification.

Heretoforein reeling silk from cocoons by automatic machinery--such, forinstance, as that shown in Letters Patent granted to me in France, No.147,621, deposited February 25, 1882, and granted May 9, 1882; inAustria, granted May 17, 1882, No. 10,629, and in German Empire, datedMarch 28. 1882, No. 19.885, and my corresponding United Statesapplication, No. 129,196, filed April 25, 1884. the filaments of thecocoons, having first been brought together and passed through the agatein the tubular revolving filamentattaching device over the water-basin,and only partially consolidated into a thread, were immediately passedaround the feeding-drum, and afterward passed through the croisure orconsolidating device during their passage to the reel. By proceeding inaforesaid manner it has been found that the threads upon thefeeding-drum,being only partially consolidated and quite wet,were apt tosplit and adhere to the drum and be wound upon it. It also happened thatthe unequal motion of the thread at the croisure or consolidating anddrying device interfered with the action of the levers that control theaction of the filament-supplying and stop-motion devices in the machinesshown in such patents and applications, in opening and closing theelectric circuits embracing such levers, such unequal motion beingcaused by the two parts of the running thread not moving upon each otherwith the same freedom at all times in consequence of inequalities in thethread.

The object of my invention is to prevent any unequal motion of thethread at the croisure affecting the levers that control the action ofthe filament-supplying and stop-motion devices, andI accomplish this byconsolidating and drying the thread at a croisu re between thefilament-attaching device and the feeding-drum.

In the drawing I have represented my improvement by a diagram.

0: represents cocoons in a water-basin, and the filaments from thesecocoons pass to the lance bout or filament attaching device I), whichconsists of a revolving hollow cylinder containing a perforated agate,through which the filaments are passed. of this cylinder there is ahook' that takes a cocoon filament from a magazine of cocoons andwrapsit around the running thread Whenever the latter falls below thestandard size. In the aforesaid application and my applica tion forpatent,No. 129,02l,filed April 23, 1884, this lance-boutand also thecocoon-magazine and the means for operating them are fully shown anddescribed, and also the electriccircuit connections and devices forstopping and starting the reel. My present invention is available as anaddition to the devices therein set forth.

The endless cord 5, pulley 6, and cord 7 to the lance-bout 1) illustratethe driving devices that may be employed to rotate the lance-bout fromthe drum D.

D represents the feeding drum, around which the thread is passed one ormore times, and from thence the thread is led around pulleys upon thelevers E F, respectively, and then goes to the reel G, upon which it iswound. This reel G is revolved at a greater surface speed than that ofthe feeding-drum D, which produces a certain tension upon the thread,and if the thread is of the maximum size the tension of the thread keepsthe lever E from its contact-point 0 If the size of the thread fallsbelow the maximum standard, then the resistance of the thread isdiminished, and the lever E falls upon its coutactpoint c and closes anelectric circuit,which brings into operation the devices that causefilaments to be added to the running thread until said thread is broughtup to the required standard of size, at which time the resistance of thethread becomes sufficient to move the lever E and break the circuit at 0All the devices thus far described and their operation are the same asthose set forth in my said applications, and do not require to berepeated.

To accomplish the object of my present invention, I make the croisure 0between the Upon the exterior filament-attaching device and the drum D.This croisure is made by passing the thread from the filament-attachingdevice I) up around a roller. 1)", then down around aroller, b and thentwisting the free end of the thread a few turns around the part of thethread passing from b to b and then leading the free end of the threadto and around the feeding-drum D; but this croisure might be made bytwisting the running thread around a stationary thread or wire.

By making the croisure between the threadattaehing device I) and thefeeding-drum D, any unequal motion of the thread at the croisure doesnot affect the regulating-levers E B, because the drum D, around whichthe thread passes, is between the levers and the croisu re, and suchunequal motion has only the effect of slightly varying the tension ofthe running thread betweenthe croisure and the feedingdrum D. The lever1 closes at c an electric circuit, if a thread breaks, to a magnet, thatbrings into action devices for stopping the reel, as set forth in mysaid applications.

H represents a pulley upon acontinuouslyrevolving shaft, which shalt maybethe drivingshaft of the machine, and from-this pulley motion istransmitted to the drum D and reel G by means of belts H H and pulleys HH.

Although I have shown the circuit-closing levers E F and their pulleysaround which the sill: filament passes between the drum D and the reelG, this present invention is available for rendering uniform the actionupon the thread in stretching" the same between the drum and reel,regardless of the devices employed in connection with the thread betweensuch drum and reel.

I claim as my invention The combination, with the revolving lancebout orfilament-attaching device 0, ofa feeding-drum, D, for drawing the threadthrough the croisure at c, a reel upon which thethrcad is wound, andmeans, substantially as specified, for rotating the reel andfeeding-drun'i and stretching the silk between the reel and drum,substantially as and for the purposes specified.
